This is a set of 10 vintage radio antenna strain glass coil insulators, with 1 being marked A.G.K. These insulators are perfect for collectors or anyone interested in vintage radio equipment. They are made of high-quality materials and are designed to withstand the wear and tear of everyday use.

The set includes a variety of styles of insulators, making it a great addition to any collection. Whether you are a seasoned collector or just starting out, these insulators are sure to impress.

I could not find any chips or cracks or flea bites on any of them. Some have some grind marks from the factory. They all need a good cleaning. Some do appear to have never been used. There is only one with a factory marking, and that is the 1 that has the A.G.K. I have no idea who might have made the others. I have heard that Pyrex made them, but I don't know how to tell who made them without markings. I am sure you collectors will know.

Each measures about 3.25 inches long and about 1 inch wide.
